In general, herbs are the scented leaves of plants that do not have woody stems and usually grow in temperate zones, while spices are the bark and fruits of plants. Vanilla is more fragrant when fresh, while the dried powdered flavor of spices is more intense.

Vanilla contains aromatic volatile oils, antioxidants, and bactericides, which not only repel flies and mosquitoes, beautify the environment, purify the air, and beautify the living room, but are also widely used in beauty, bathing, diet, and medicine.
